(In addition to the official list above, MMAjunkie.com has confirmed that Jon Koppenhaver is expected to join the cast as a replacement for an injured fighter at some point during the season.)

Current welterweight champion Matt Serra and former champ Matt Hughes serve as coaches this season. The two fighters aren’t exactly the best of friends, and Spike TV Senior Vice President of Sports and Specials Brian J. Diamond told MMAjunkie.com that the friction will be evident.

“They’re not going to disappoint,” Diamond said. “In their own way, they are incredible characters. They’re completely polar opposites — not just geographically (but also) in terms of who they are as people and how they fight. There are a lot of surprises with those two guys along the way.”

After the debut episode’s 11 p.m. time slot, the series will then air on Wednesdays at 10 p.m. ET/PT.

The series’ live finale is expected to take place Dec. 8 at The Palms Las Vegas.

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
